“ According to the standards body, 3GPP, the radio frequency spectrum used by LTE networks ranges from 700 MHz to 2.7 GHz. In theory, LTE peak data rates are 75 Mb/s for the uplink and 300 Mb/s for the downlink when using a multiple-input multiple-output (MIMO) antenna system, also referred to as spatial multiplexing.
The frequency bands for 5G networks come in two sets. Frequency range 1 (FR1) is from 450 MHz to 6 GHz, which includes the LTE frequency range. Frequency range 2 (FR2) is from 24.25 GHz to 52.6 GHz. The sub-6 GHz range is the name for FR1 and the mmWave spectrum is the name for FR2.
In theory, the peak data rates for a fully mature 5G network are 20 Gb/s downlink and a 10 Gb/s uplink, as standardized by the International Telecommunications Union.”
Technical and industrial standards are not academic exercises Their viability heavily depends on the adoptions by the international community. A case in point, two decades ago China introduced its own wireless encryption standard WAPI. But the West boycotted it. In the end, China backed off. That was in the era when China was seen as a frenemy.
Now, the West regards China as a rival. We can expect that China's standards will only be adopted in China, not even likely to be used by Russia. Then China will be further separated from the rest of the world. If the past was any indication, we all know how far China can go as an isolated middle kingdom.
——欧美制定“国际标准”,不也是要“在全球推广自己的技术”么?不也是要“给外国竞争对手增加进入自己市场的难度”么?中国这么做,叫做有样学样。如今的中国已经不再追求“与世界接轨”了,中国要制定自己的标准。欧美当然也可以制定自己的标准,没人拦着,但不能要求中国不能有自己的标准,只能遵守欧美制定的标准。大不了大家分道扬镳,你搞你的我搞我的。你的脸书别进我中国,我的微信也被你禁止,大家各自玩各自的。总之,在5G通讯、物联网、人工智能、大数据、云计算等未来经济的主流领域,中国是不会再“服从”欧美的技术标准的,除非你让我也参与标准的制定,咱们共同来制定“国家标准”。如果像欧美今天这样,企图把中国排斥在标准的制定过程外,那么中国必将自搞一套不同的标准。第一,如今我的技术已不比你差多少,第二,我的市场更不比你的小,我为何要买你的账?无非大家再回到NTSC制式和PAL制式之争嘛,有什么呢?过去世界在不同的制式下,不也照样舞照跳马照跑吗?未来也可以啊。以4G技术的市场应用来看,欧美日韩加澳新——整个西方世界,也不过200多万个基站,而中国一国就接近400万个基站;中国已经做到了一部手机在手,万事搞定的程度,西方有哪一个国家做到了?所以,有理由相信,未来5G、6G的市场应用,中国的市场规模也必将远超西方市场。再加上与中国经济紧密的东盟、中国帮助建设的一带一路国家,和中国影响力绝对占优的非洲,预计都会采用中国的标准——因为这些国家和地区必须与中国接轨,才能发展进步、万事顺利;若与中国脱轨,就意味着发展受阻,诸事不顺。欧美标准,就让欧美自己去玩吧,它若能玩得大,算他们的本事,我们予以祝贺。但要我们也跟随欧美标准,则谢谢侬哦伢叔。所以,欧美想要“阻止中国标准”,这是做不到就是做不到的事情,最多就是两个标准并行于世。你要进入我的市场,就得按照我的标准来;我要进入你的市场,就得按照你的标准来。最后就是大家竞争谁的市场更大,谁就在这新一轮的经济中,赚到更多的钱。中国,就凭着自身比整个西方世界更大的国内市场,就已经立于不败之地了。若再加上东盟市场、一带一路市场、非洲市场,欧美排斥“中国标准”的努力,注定失败。
